What happens to the endocrine system as people age?
Hormone production by the endocrine system declines with age in all animal species that have been tested to date. As an example, in humans, the amount of growth hormone after the age of 20 to 30 falls about 14% per decade, so that the total 24-hour growth hormone production rate is reduced to half by the age of 60. In numerical values, we produce on a daily basis about 500 micrograms at 20 years of age, 200 micrograms at 40 years, and 25 micrograms at 80 years old. “Elderly” levels are reached by age 35-40. The American Association of Endocrinology and the American College of Endocrinology suggest that hormone deficiency is an age-related event characteristically defined as a cluster of easy to recognize symptoms that include: • Fatigue • Increased weight and abdominal obesity • Decreased lean body mass, muscle mass, and strength • Decreased exercise capacity and physical performance • Cold extremities • Reduced vitality • Impaired sense of well-being • Poor sleep • Emotional instabili
